摘　　要：随着环保需求的增加和新能源技术的发展,新能源专用车辆在我国得到了广泛应用。但是,新能源专用车辆的速度控制策略仍存在研究空白。本文选取新能源专用车辆为研究对象,研究其速度监控策略,首先,根据车辆的动力学模型和驾驶行为模型建立了车速预测模型;然后,设计了一种新的速度控制策略,该策略采用了混合反馈-前馈控制结构,并结合模型预测控制和滑模控制等多种控制方法;最后,在各种典型的驾驶工况下进行了仿真验证。研究结果表明,新的速度控制策略可以有效地改善车辆的速度跟踪性能和能源利用效率,同时还能保证驾驶者的舒适性。该研究为新能源专用车辆的研发和应用,特别是其控制策略的选择和优化提供了重要的参考。With the increase of environmental protection demand and the development of new energy technology,new energy special vehicles have been widely used in China.However,there is still a research gap in the speed control strategy of new energy vehicles.In this paper,new energy vehicles are selected as the research object to study their speed monitoring strategies.Firstly,the vehicle speed prediction model was established according to the vehicle dynamics model and driving behavior model.Then,a new velocity control strategy was designed,which adopted a hybrid feedback-feedforward control structure,combined with multiple control methods such as model predictive control and sliding mode control.Finally,simulations are carried out under various typical driving conditions.The results show that the new speed control strategy can effectively improve the speed tracking performance and energy efficiency of the vehicle,and at the same time ensure the comfort of the driver.This study provides an important reference for the development and application of new energy special vehicles,especially the selection and optimization of their control strategies.
